srLo CONSTRUCTION.

Application filed November 123, 1924. Serial No. 750,579.

To all whom t may concern:

Be it known that l, ADoLrr-r I. ANDnnsoN, a citizen of the United States, residing at Zumbrota, in the county of Goodhue and State of Minnesota, have invented certain new and useful linproveinents in a Silo Construction, of which the following is a specification.

VThis invention relates to the construction of silos and the like, and has for one of its objects to simplify and improve the construction and increase the eihciency and utility of devices of this character.

Another object of the invention is to provide a device of this character constructed in a plurality of sections or panels which may be constructed in duplicate at some central plant or factory and shipped knocked down and erected where the completed silo or other structure is to be located.

Another object of this invention is to provide a device of this character, constructed in a plurality ofsections or panels of novel form and arrangement, and capable of producing a plurality of continuousl vertical air passages or spaces when arranged end to end and side by side.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention- Figure 1 is a side elevation, partly in section, of a silo constructed in accordance with my invention.

Figure 2 is a sectional detail through the feed and discharge doors.

Figure 8 is a sectional detail of the iniproved silo through the main wall portion.

Figure l is a transverse section on the line of Figure 1.

Figure 5 is a transverse section on the line 5-5 of Figure 1.

Figure 6 is a side elevation of a portion of the device illustrating the construction and arrangement of the combined feed and discharge doors.

Figure 7 is a detached perspective view of one of the wall panels or sections.

Figure 8 is a sectional detail illustrating a modication in the construction.

The improved device is supported on a suitable foundation or base of concrete, or the like, and preferably including an annular vertical wall 10 and a horizontal bottom 11, the wall portion surrounded by earth or tamping indicated at 12.

The upper edge of the wall 10 extends a short distance above the level of the ground 12 as shown. For the purpose of illustration the base portion of the improved structure is shown embedded in the ground, but it will be understood that it is not desired to limit the device to this spccilic construction, as the base or foundation may under some circumstances and in some climates be disposed entirely above the ground, or otherwise placed. Supported on the bottom 11 and against the inner face ofthe vertical walls 10 and for a distance above the ground, are a plurality of sections or panels engaging edge to edge and one above the other, as represented more particularly in Figure 1, to form the walls of the silo when completed. The panels or sections are alike except that they are of varying lengths, and the description of one will suliice for all. Each panel comprises spaced vertical side members 13 of 2 X l joists or stringere and transverse members 14, of matched siding, ship lap, or the like nailed together, to produce the structure disclosed in Figure 7. The side aces of the stringers 13 are bevelled so that when a number of the panels are disposed side by side the edges will be closely enand form a polygonal ligure or panel as shown in Figure 4. The panels will be of varying lengths and arranged to break joints, as indicated in Figures 1 and 6.

ln practice a certain number of the panels will be one-half the length of the remaining panels, and will be alternated therewith `at the upper and lower ends of the structine, as shown. vThe con It ng side .rails 13 of the panels will be connect d in any suitable 1' anner preferably by bolts, so that they can be readily connected and disconnected. At their lower ends the side rails 13, or the portions within the foundation walls 10, are left without the covering members 14, as indicated in Figure 1, and the spaces between the uncovered side rails filled with concrete, or the like, as represented in Figure 5.

For the purpose of illustration a structure with eight vertical rows or sets of the panelsis shownl` and with two full length panels and two half length panels in each vertical row, but a structure of any required number of the panels both vertically and transversely may be constructed, as required.

At their lower ends the rail members 13 of the lower panels are seated on base members or sills 15 resting on the bottoni-11 of.

tic material indicated atl? with its inner face convex, as shown, so that when the requisite number `of the panels are united to complete the Walls of the structure, 'the inner faces of the series of connected panels form a complete circular or cylindrical interior of the silo. One verticalrow of the panels is omitted, and this space occupied by a plurality of detachable doors or filler members, each formed of side rails 18 and transverse members 19.

Attached to the confronting faces of the side rails 13 of the panels next to :the space for the detachable doors or fillers, are continuous door frame members 20, each hav-I ing` a longitudinally directed rebate or seat 21 in the inner faces to receive the door sections, as shown. rlfhe door frame members 2O are connected and supported at suitable intervals by stay members 22 which also serve` as ladder steps to enable the operator to reach the doors when they are to be removed as the silo material is discharged, in the usual manner.

A Yroof of suitable construction Vrepresented at 23 is arranged over the completed` walls and provided with a ventilator device, represented conventionally at 2a.

The panels which form they side walls and the detachable door member being uniform in size and form, can be manufactured in quantities at a central plant, or manufactured and shipped knocked down or crated to the locality where the silo is to be erected, and the parts cheaply .and

quickly assembled and united by any person withoutprevious skill or knowledge.

The plastic lining may be of any required thickness to correspond to the climate Where the silo is erected, and to protect the contents from frost.

By forming the panels with the polygonal outer form and convex or arching` inner form of cementitious material which sets solidly when dried, a very rigidA truss structure is produced, which when the panels are united very eflectually resists any strains to which the structure may be subjeeted,

ln Figures 4t and 7 the screen material portion 16 is shown spaced at a short distance from the side members 13 and reinforcing strips 25 interposed at spaced intervals between the side members, and in Figure S, the screen material is shown bearing directly against the coveringfmembers 141. Either construction may be employed.

The apparatus is simple in construction, can be inexpensively-manufactured and in large quantities, at a centralk factory, as before stated] T he'preferred embodimentof the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications Within the scope of the claimed,l invention may be made in the construction Without kdeparting from the principle of the invention or sacrificing any of its advantages.

Having thus Y described the invention what is claimed is:y

A wall formed of units engaging edge to edge and end to end, each unitbeing formed of impervious spaced side members, impervious outer members connected to the outer edges of the side members, an inner membercapable of holding a coating of platic material and a coating of plastic material applied over said inner member, the spaces between the members constituting continuous dead air chambers when i the units are arranged to form a wall.

In testimony whereof, I afHx -my signaY ture hereto.`

ADOLPH I. ANDERSON.
